Dementia isn’t actually a disease but a group of symptoms caused by several other conditions. As estimated, over 50 million people are living with dementia worldwide.

The most common cause of dementia is Alzheimer’s. Studies also say that about 60%-80% of people with dementia are suffering from Alzheimer’s. However, there are 50 other causes of dementia too.

In general, symptoms of dementia may improve with treatment. But some of the diseases that cause dementia aren’t treatable.

Let’s learn more about the syndrome and when to visit a Mental Health Rehabilitation Center for help.
